The amount of wood required to build a house can vary significantly depending on various factors, including the size and design of the house, the construction method, and the local building codes and regulations. Typically, the structural framing of a house, including the walls, floors, and roof, requires a substantial amount of wood.
To provide a rough estimate, a conventional wood-framed house in the United States might require anywhere from 8,000 to 20,000 board feet of lumber. This estimate can vary based on the size of the house, the number of stories, and other factors. It's important to note that this estimate only includes the framing and doesn't account for other building materials such as siding, insulation, and interior finishes.
It's always best to consult with an architect, contractor, or construction professional who can assess the specific requirements of the house you have in mind and provide a more accurate estimate based on your location and the desired specifications of the project.
